Abstract (en)

[origin: US2019300839A1] The present disclosure provides methods for controlling oxygen concentration during aerobic biosynthesis, e.g., fermentation. The method may comprise feeding an oxygen-containing gas into a vessel including a fermentation feedstock and reacting the fermentation feedstock with the oxygen-containing gas to form a broth including a gaseous phase dispersed within the broth. The gaseous phase may comprise any unreacted oxygen from the oxygen-containing gas. The method further includes reducing the concentration of the unreacted oxygen in the dispersed gaseous phase to less than the limiting oxygen concentration (“LOC”) for flammability before separating the gaseous phase from the fermentation broth. The concentration of the unreacted oxygen in the gaseous phase is reduced by employing oxygen removal schemes or oxygen dilution schemes.
